为了完成这个项目,需要掌握如下技术:
Java基础知识
第一步:创建 Maven webapp 项目,首先新建工程,选择 Maven 标签,然后勾选上【Create from archetype】选择 webapp:
点击下一步,填写上【GroupId】和【ArtifactId】:

在【spring-mybatis.xml】中完成 spring 和 mybatis 的配置:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<!-- 配置数据库相关参数properties的属性:${

<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 数据库连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxPoolSize" value="${c3p0.maxPoolSize}"/>
<property name="minPoolSize" value="${c3p0.minPoolSize}"/>
<property name="autoCommitOnClose" value="${c3p0.autoCommitOnClose}"/>
<property name="checkoutTimeout" value="${c3p0.checkoutTimeout}"/>
<property name="acquireRetryAttempts" value="${c3p0.acquireRetryAttempts}"/>
</bean>
<!-- 配置SqlSessionFactory对象 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource"/>
<!-- 扫描entity包 使用别名 -->
<property name="typeAliasesPackage" value="com.jdl.model"/>
<!-- 扫描sql配置文件:mapper需要的xml文件 -->
<!--<property name="mapperLocations" value="classpath:mapper/*.xml"/>-->
</bean>
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 配置基于注解的声明式事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 配置扫描Dao接口包,动态实现Dao接口,注入到spring容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!-- 给出需要扫描Dao接口包 -->
<property name="basePackage" value="com.jdl.dao"/>
</bean>
<!-- 扫描dao包下所有使用注解的类型 -->
<context:component-scan base-package="com.jdl.dao"/>
<!-- 扫描service包下所有使用注解的类型 -->
<context:component-scan base-package="com.jdl.service"/>
</beans>
在【spring-mvc.xml】中完成 Spring MVC 的相关配置:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 扫描web相关的bean -->
<context:component-scan base-package="com.jdl.controller"/>
<!-- 开启SpringMVC注解模式 -->
<mvc:annotation-driven/>
<!-- 静态资源默认servlet配置 -->
<mvc:default-servlet-handler/>
<!-- 配置jsp 显示ViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
在【jdbc.properties】中配置 c3p0 数据库连接池:
jdbc.driver=com.mysql.jdbc.Driver
#数据库地址
jdbc.url=jdbc:mysql://127.0.0.1:3306/student?useUnicode=true&characterEncoding=utf8
#用户名
jdbc.username=root
#密码
jdbc.password=123
#最大连接数
c3p0.maxPoolSize=30
#最小连接数
c3p0.minPoolSize=10
#关闭连接后不自动commit
c3p0.autoCommitOnClose=false
#获取连接超时时间
c3p0.checkoutTimeout=10000
#当获取连接失败重试次数
c3p0.acquireRetryAttempts=2
在【logback.xml】中完成日志输出的相关配置:
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{
HH:mm:ss.SSS} [%thread] %-5level %logger{
36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT"/>
</root>
</configuration>
以上就完成了 SSM 框架的基本配置:
第四步、新建一个index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>首页</title>
<style>
div{
padding: 300px 650px;
}
</style>
</head>
<body>
<div>
<h1>欢迎来到首页</h1>
</div>
</body>
</html>
搭建完毕!
